A new GM engine is currently in its final stages of development, GM Authority has exclusively learned from sources familiar with the matter.
The planned GM engine will be a turbocharged 2.5L four-cylinder powerplant. It will be part of The General’s CSS or Cylinder Set Strategy engine family, which currently consists of four models.
The table below lists the CSS or Cylinder Set Strategy GM engine family, including maximum horsepower and torque.
|Turbo 1.3L I3||Turbo 2.0L I4||Turbo 2.7L I4||Turbo 2.7L I4||Turbo 2.7L I4|
|Max Horsepower||155 @ 5,600||237 @ 5,000||237 @ 5,600||310 @ 5,600||325 @ 5,500|
|Max Torque||174 @ 1,600||258 @ 1,500 to 4,000||260 @ 1,200 to 4,000||430 @ 3,000||380 @ 2,000 to 4,000|
Among the other powerplants in the family, the turbocharged 1.3L I3 L3T engine is used to provide motivation for smaller vehicles like the Chevy Trailblazer and the Buick Encore GX. The turbocharged 2.0L I4 LSY gasoline engine is suited to a wider range of applications, powering the Buick Envision, Cadillac CT4, Cadillac XT4, Cadillac XT5, Cadillac XT6, Chevy Blazer, and GMC Acadia.
The family also includes a pair of 2.7-liter powerplants. The turbocharged 2.7L I4 L2R gasoline engine is a cost-effective version of the L3B and can be used in vehicles up to the size of a full-size pickup, serving as an option for the Chevy Colorado.
Finally, the turbocharged 2.7L I4 L3B gasoline engine is a clean-sheet design GM engine and has a high-output version generating extra torque for light-duty pickup trucks and possibly other vehicles.
The L3B is found in the Cadillac CT4-V (where it develops 325 horsepower and 380 pound-feet of torque), the Chevy Colorado, the Chevy Silverado 1500, the GMC Canyon, and the GMC Sierra 1500. GM Authority exclusively discovered that the recently updated L3B engine will actually make 430 pound-feet of torque in the 2022 Silverado 1500 and 2022 Sierra 1500, instead of 420 pound-feet originally announced.
